Add HSP Dependency

Overview

After completing the first step, a dynamic shared package has been created in our project. As shown below, the project now contains a main module (entry) and a dynamic shared package (shared_library).

If entry needs to access code or resources in shared_library, it must be linked to shared_library.

There are 3 solutions to add dependencies:

Mapping Solution 1

Introduce the shared package in entry module oh-package.json5 file under dependencies with the following format:

"mapped_directory_name": "file:../folder"
  • The folder refers to the shared package you created.
  • The mapped directory name is the name for the generated dependency kit, it must be the same as the name defined in oh_package.json5 from the shared package.

You can place the mouse over the warning area to see a prompt, and then click Run ohpm install.

After installation, the shared package will be mapped into the entry module, under its oh_modules directory.

Mapping Solution 2

Besides Mapping Solution 1, you can also use the following approach:

Introduce the shared package in entry module oh-package.json5 file under dependencies with following format:

"@xx/mapped directory name": "file:../folder"

The underlying mechanism is the same as in Method 1. The difference is that an @xx directory will be created under the oh_modules directory.

Mapping Solution 3

You can also install the dependencies through the command line.

Navigate to your entry module directory, and run the following command: 

ohpm install ../{mapped directory name}

After the command is executed, the dependency will be automatically added to oh-package.json5, and the mapping files will be generated.
